Indeed, this is a very interesting show, however the sound is horrible. It's like that Star Trek with the salt sucker monster; all of the salt has ben sucked out of this beastie. The power and beauty of the music wants to come out,
i.e. you can tell this was a great show, but it is as if the show was recorded inside of a plastic bag. I couldn't even finish the show. Too depressing. I threw the discs out.
Maybe try the taper version. It has a lot of clapping and stuff, but to my ears it sounds way better.
